Another Walk through the World of Chiral Dynamics
February 28, 2020
Chiral dynamics is a pretty mature field. Nonetheless, there are many exciting new
developments. In this opening talk, I consider S-wave, isospin-zero pion-pion scattering and
the calculation of the width of the lightest baryon resonances at two loops. New insights into
the chiral dynamics of charm-strange mesons are discussed as well as recent results on the
flavor decomposition of the pion-nucleon $\sigma$-term. I end with a short wish-list of lattice
QCD tests pertinent to chiral dynamics.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
